It's a very common misunderstanding since the Java Persistence API was
developed as part of the EJB 3.0 JSR. Part of the simplicity of Java
Persistence entities comes from "decomponentizing" them and ensuring
that they can be used independently of EJB components. Of course, it's
still extremely important that they integrate well with Session Beans
and Message-Driven Beans.
Going forward, EJB and the Java Persistence API are being developed
within separate JSRs (318 and 317).

Likewise. I'll be presenting on EJB 3.1 and doing a talk with Linda
DeMichiel on EJB 3.0. Hope to see you there!
